We've recently added a new docs page to include more information on connecting HoloLens to cellular networks. You can find it at https://aka.ms/HL5G. While hotspot / WiFi is sufficient for most use cases, there are still times when tethering provides some benefit (for example ultra low latency or Azure Remote Rendering).
Though we're unable to provide a curated list of cellular devices that are compatible with HoloLens 2, we're hoping folks in our community can share your own experience with the devices that have worked for you.
Thanks in advance for sharing, and thank you for being part of the community!

I have an unlocked Samsung S10 I am attempting to connect to HL2 via USB-C. It has not showed up as a connection as yet, can you share your specific Note 10 settings?
I am also currently testing the following devices with a goal of connecting HL2 to CBRS LTE networks;
Inseego Mifi 8000 - Can select USB Tether mode when HL2 connects but it does not show as available interface.
AMIT IDG120 - Not detected, tried both Windows Moe and Chromebook Mode
Sercomm Wingle - Not detected even though it is an RNDIS compatible device.
I'll share any progress as I work with the various vendors to develop a working solution.
Thanks all!
JR

I usually use my Samsung Galaxy S20+ 5G with mobile hotspot for off-site meetings where the HoloLens 2 is connected over Wi-Fi to the phone's hotspot. I just tried it with USB tethering and it seems to be working as well. USB Tethering can be great to avoid more Wi-Fi inference in certain environments with lots of signals around but keep in mind that the phone will be charged using the HoloLens 2 battery if you connect it with USB. Would be good if this can be turned off.

Thank you wez_p, JR_Celona and Rene Schulte. Really appreciate the details shared. Feedback heard on the charging part. I've asked if there's anything we can do but haven't heard back yet. Not sure if that's even something that can be addressed in the firmware. It looks like there are some USB-C hubs that claim to do pass-through power delivery. I wonder if you could use one of those to charge and do data at the same time. Understand of course that would be a bit bulky.

I saw in your post that you were receiving some dongles and handsets to test. By any chance are these 5G dongles or are they still 4G? If you have received them, by any chance have you had a chance to test them?

Is there any possibility to connect network adapters without RNDIS ?
I've tested Telit 4G (LM 940) Modem and 5G (FN980) without any success.
You can control Cellular Modems with AT-Commands over serial connection.
Is this possible with hololens 2 ?

Hello All,
By any chance has anybody managed to connect a device to a Stand Alone (SA) private 5G network and then used that device so the HoloLens could connect to? A customer got in touch that they want to do a PoC with HL and 5G but that the network is a private SA 5G network and not a public one. So far they haven't been able to find a device that connects to one of these networks. The 5G enabled mobile phones can't connect to it, thus they haven't been able to use that as a hotspot/tethering option.

I finally got a response back about HoloLens charging the phone when tethered.
In short, this is by design. We provide power because we wanted to support external storage. While there are some methods for devices to negotiate who charges who (for example TRY.SNK), those were still being ratified at the time HL2 design was finalized. Unfortunately it doesn’t appear support can be added now.
They did offer two possible workarounds, but neither are tested or supported by Microsoft:
I know that's not the answer some were hoping for, but I do still hope it helps.
